Report  on  Commercial  Fertilizers,  1923. 

E.  M.  Bailey,  Chemist  in  Charge,  Analytical  Laboratory. 


PROVISIONS  OF  'THE  FERTILIZER  LAW. 

The  provisions  of  the  fertilizer  law  as  it  affects  dealers  in  com- 
mercial fertilizers  in  this  State  have  been  explained  in  previous 
bulletins  of  this  Station  and  the  text  of  the  law  may  be  found  in 
Chapter  204  of  the  Public  Acts  of  1919.  Certain  points  of  interest 
and  importance  to  both  buyers  and  sellers  of  fertilizers  may, 
however,  be  briefly  restated. 

Significance  of  the  Term  "Commercial  Fertilizers". 

Explaining  what  is  meant  by  the  term  "commercial  fertilizers" 
the  law  says: 

"The  term  'commercial  fertilizers'  shall  be  construed  to  mean  any  and 
every  substance  imported,  manufactured,  prepared  or  sold  for  fertilizing  or 
manuring  or  soil  amendment  purposes,  except  barnyard  manure  and  stable 
manure  which  have  not  been  artificially  treated  or  manipulated,  marl  and  lime. 
Cottonseed  meal,  rapeseed  meal,  castor  pomace  and  all  other  vegetable  prod- 
ucts used  as  fertilizers,  including  the  ashes  of  cotton  hulls  and  wood  ashes, 
shall  be  included  as  fertilizers  within  the  meaning  of  this  act  and  separate 
analysis  fees  shall  be  paid  on  each  different  grade  which  is  sold  or  offered  for 
sale  in  the  state.  The  person  responsible  for  paying  the  fees  above  prescribed 
may  deduct  from  the  total  tonnage  sold  such  sales  of  cottonseed  meal  or  other 
vegetable  products  as  are  made  to  anyone  who  gives  a  written  certificate  on  a 
form  supplied  by  the  Connecticut  Agricultural  Experiment  Station  stating 
that  the  material  bought  by  him  was  to  be  used  exclusively  for  feed  and  not 
for  fertilizer." 

Cottonseed  meal  is  a  fertilizer  within  the  meaning  of  the  Statute 
but  it  is  provided  that  when  this  product  is  sold  for  feeding  purposes 
only,  it  shall  be  exempt  from  the  tonnage  tax. 

The  status  of  cottonseed  meal  under  the  fertilizer  law  has  been 
clearly  stated  in  a  bulletin1  from  this  Station  from  which  the 
following  may  be  quoted : 

Registration  and  analysis  fees.  "Each  brand  of  cottonseed  meal  must  be 
registered  on  forms  provided  by  this  Station  and  an  analysis  fee  of  ten  dollars 
paid  on  it  before  it  is  sold,  offered  or  exposed  for  sale,  and  on  the  first  day  of 
January  annually  thereafter. 

"A  distinctive  name  constitutes  a  distinct  brand.  If  shipments  have  dif- 
ferent guaranties  of  composition  they  are  held  to  be  different  brands." 


iBull.  of  Information  No.  9,  1919. 


4  CONNECTICUT   EXPERIMENT   STATION   BULLETIN   250. 

Branding  or  tagging.  "Since  nitrogen  is  the  only  fertilizer  ingredient  con- 
sidered in  the  trade  in  cottonseed  meal  no  guaranty  of  phosphoric  acid  or 
potash  is  required.  If  either  is  guaranteed  by  the  manufacturer,  however,  an 
additional  fee  of  ten  dollars  must  be  paid  on  each  element.  The  statement  of 
composition  now  legal  for  feeds  may  be  used  hereafter  if  the  precentage  of 
nitrogen  is  stated. 

"Note  that  the  law  regarding  feeding  stuffs  forbids  the  use  of  metal  in 
attaching  tags  and  requires  that  each  package  shall  be  branded  or  tagged  with 
the  statement  required  by  law." 

Duties  of  shippers.  "It  is  assumed  from  correspondence  with  shippers 
outside  the  state  that  they  will  register  the  brands  which  they  sell  in  Connect- 
icut, will  pay  analysis  fees  as  has  been  done  in  the  past  by  manufacturers  of 
commercial  fertilizers,  and  will  semi-annually  thereafter  pay  the  tonnage  fees. 

"They  will  report  to  this  Station  their  total  sales  and,  if  they  wish,  may 
report  what  part  has  been  sold  for  feed  exclusively.  From  the  reports  of 
dealers  within  the  state  it  will  be  possible  to  determine  quite  closely  the, 
amounts  of  each  brand  actually  used  as  feed. 

"In  the  case  the  jobber  outside  the  state  neglects  or  refuses  to  register  a 
brand,  the  dealer  who  sells  it  within  the  state  is  responsible  under  the  law." 

Duties  of  dealers.  "Dealers  are  required  to  file  with  the  director  of  the  Sta- 
tion on  July  first  of  each  year  and  semi-annually  thereafter  a  sworn  statement 
of  their  total  sales  of  each  brand  of  cottonseed  meal  and  the  amount  of  each 
sold  exclusively  for  feed,  during  the  preceding  six  months." 

Requirements  to  be  Complied  with  by  Sellers  of  Commer- 
cial Fertilizers. 

The  seller  is  responsible  for  the  proper  labeling  of  each  pack- 
age, for  the  registration  at  the  Station  of  every  brand  sold  by  him 
and  for  the  payment  of  the  analysis  fee,  before  offering  for  sale, 
and  annually  thereafter  on  January  1st. 

The  seller  must  also,  on  the  1st  of  January  and  July,  report 
the  tonnage  of  fertilizer  sold  within  the  preceding  six  months  and 
pay  to  the  director  of  the  Station  a  tonnage  fee  of  6  cents  per  ton. 

On  request,  copies  of  the  law  and  blanks  for  registration  and  for 
tonnage  reports  will  be  supplied  by  the  Station. 

If,  however,  proper  labeling,  registration  and  payments  have 
been  provided  for  by  the  manufacturer  of  the  brands  or  by  another 
responsible  person,  all  sellers  of  such  brands  are  released  from  the 
above  mentioned  requirements.  The  retailer,  therefore,  should 
assure  himself  that  the  requirements  of  the  law  have  been  met  by  the 
manufacturers  of  the  brands  which  he  handles,  or  himself  be  prepared 
to  meet  all  these  requirements. 


Precautions  to  be  Observed   in   Drawinc   Samples  for 

Analysis. 

The  analysis  of  a  fertilizer  is  of  no  value  unless  the  sample 
analyzed  represents  as  nearly  as  possible  the  stock  from  which  the 
sample  was  drawn.  The  law  prescribes  the  procedure  to  be  follow- 
ed by  authorized  agents  of  this  Station  when  taking  official  samples 
for  analysis  as  follows: 


REGISTRATIONS.  5 

"When  samples  are  taken  from  fertilizers  in  bags,  a  tube  shall  be  used,  and 
it  shall  be  inserted  at  one  end  of  the  bag  and  shall  pass  substantially  the  entire 
length  of  the  bag,  so  as  to  take  a  core  of  the  macerial  being  sampled  from  sub- 
stantially the  entire  length  of  the  bag.  Samples  thus  taken  from  individual 
bags  shall  be  thoroughly  mixed,  and  the  official  samples  shall  be  taken  from 
the  mixture  so  drawn  by  the  method  known  as  'quartering.'  Samples  of 
fertilizer  taken  as  herein  provided  shall  be  taken  from  at  least  five  per  centum 
of  the  separate  original  unopened  packages  in  the  lot,  for  the  mixture  from 
which  the  official  samples  shall  be  taken.  If  less  than  one  hundred  bags  are 
in  the  lot,  at  least  five  bags  shall  be  sampled;  if  less  than  five  bags,  all  shall  be 
sampled.    Broken  packages  shall  not  be  sampled." 

The  Station  is  called  upon  each  year  to  analyze  a  large  number 
of  samples,  drawn  and  submitted  by  individuals,  representing 
fertilizers  bought  by  them  for  their  own  use.  The  purpose  of  the 
sender  is  to  find  out  whether  the  mixture  contains  the  amounts  of 
plant  food  which  are  guaranteed,  and,  if"  it  does  not,  to  secure 
evideDce  upon  which  to  base  a  claim  against  the  seller  for  the 
shortage.  It  is,  therefore,  necessary  that  the  sample  be  taken  essen- 
tially in  the  way  prescribed  by  law  and  in  the  presence  oj  a  witness 
so  that  there  can  be  no  question  about  the  fairness  of  the  sample.  The 
Station  will  supply  to  any  applicant  a  form  upon  which  the  sender 
should  give  the  necessary  information  and  submit  it  with  the 
sample.  This  makes  the  sample  of  public  interest  and  value, 
which  is  the  only  justification  for  doing  the  work  at  State  expense; 
and  it  is  also  the  sender's  protection  in  case  the  validity  of  the 
sample  is  questioned.

I.     RAW    MATERIALS    CHIEFLY    VALUABLE    FOR 
NITROGEN. 

NITRATE  OF  SODA. 

Twenty-four  samples  were  examined  and  results  are  given  in 
Table  I. 

Chemically  pure  nitrate  of  soda  contains  16.47  per  cent,  of 
nitrogen  but  commercial  nitrate  of  soda  or  "Chili  saltpeter"  con- 
tains from  15  to  16  per  cent,  which  is  equivalent  to  91  to  97  per 
cent,  nitrate  of  soda.  The  impurities  in  the  commercial  article 
are  chiefly  common  salt  and  water.  Plants  respond  quickly  to 
nitrogen  in  this  form  because  it  is  directly  assimilable.  The  residue 
which  nitrate  of  soda  leaves  in  the  soil  is  alkaline. 

At  the  prices  quoted  for  this  material,  nitrogen  has  cost  from  17. 2 
cents  to  24-4  cents  per  pound,  the  average  cost  being  20.6  cents. 


SULPHATE  OF  AMMONIA. 

Nine  samples  were  analyzed  and  the  results  are  given  in  Table  II.

Pure  ammonium  sulphate  contains  21.2  per  cent  of  nitrogen, 
but  the  article  of  commerce  usually  contains  about  20.5  per  cent. 
Four  of  the  samples  examined  this  year  were  of  a  high  degree  of 
purity  containing,  or  closely  approaching,  21  per  cent. 

Like  nitrate  of  soda,  ammonium  sulphate  is  readily  soluble  in 
water  and  quickly  diffuses  through  the  soil.  Since  it  does  not 
leach  out  from  the  soil  so  rapidly  as  does  nitrate  of  soda  and 
because  its  assimilation  by  plants  is  somewhat  slower  it  has  an 
advantage  over  nitrate  of  soda  in  wet  seasons  and  it  sustains 
growth  over  a  longer  period. 

Prices,  so  far  as  quoted  to  us,  ranged  from  $70  to  $83.60  per  ton 
making  the  cost  of  nitrogen  -per  pound  from  16.7  cents  to  20.1  cents 
the  average  being  18.7  cents.

CASTOR  POMACE. 

Seventy-one  samples  have  been  analyzed  and  results  are  given 
in  Table  III. 

Castor  pomace  is  the  residue  left  after  extracting  the  oil  from 
the  castor  bean.  Live  stock  will  eat  the  pomace  greedily  and 
since  it  contains  a  deadly  poison  care  should  be  taken  not  to  store 
it  where  it  will  be  accessible  to  farm  animals. 

This  material  has  been  used  in  increasing  quantities  in  the  last 
two  years  as  a  source  of  organic  nitrogen  in  mixed  fertilizers  as  a 
supplement  to  cottonseed  meal.  It  contains  from  4.5  to  5.5  per 
cent  of  nitrogen  the  availability  of  which  is  about  equal  to  that  of 
dried  blood  and  cottonseed  meal.  Besides  nitrogen,  it  contains  on 
the  average  about  1  per  cent  of  potash  (K20),  and  2  per  cent 
of  phosphoric  acid  (P2O5),  the  latter  largely  or  entirely  available. 

The  average  nitrogen  content  of  samples  analyzed  during  the 
past  year  is  5.1  per  cent  and  the  average  ton  price,  so  far  as  prices 
are  recorded  with  us  confidentially  or  otherwise,  is  $34.51.  Thus 
the  cost  of  nitrogen  per  pound  in  this  material  has  been  83.8  cents, 
no  allowance  being  made  for  the  phosphoric  acid  and  potash  which  it 
contains. 

COTTONSEED  MEAL. 

The  standard  commercial  grades  of  cottonseed  meals  used  for 
feeding  purposes,  and  the  grades  chiefly  sold  for  fertilizer,  are 
guaranteed  as  follows: 

36  per  cent  protein  containing  5.76  per  cent  nitrogen  equivalent 
to  7.00  per  cent  ammonia. 

4-1  per  cent  protein  containing  6.56  per  cent  nitrogen  equivalent 
to  8.00  per  cent  ammonia. 

4-3  per  cent  protein  containing  6.88  per  cent  nitrogen  equivalent 
to  8.8  per  cent  ammonia. 

One  hundred  and  seventy-nine  samples  of  cottonseed  meal  have 
been  analyzed  and  results  are  given  in  Table  V.  These  samples 
belong  largely  to  the  three  groups  just  named.  Three  have  odd 
guaranties  and  in  twelve  cases  no  statement  of  guaranty  could  be 
secured. 

Information  as  to  prices  was  not  afforded  in  some  cases  and  in 
others  it  was  confidential,  but  the  cost  per  pound  of  nitrogen  has 
been  calculated  based  upon  the  average  of  such  ton  prices  as  were 
quoted  to  us  whether  confidentially  or  otherwise. 

Samples  which  failed  to  meet  their  guaranties  by  more  than  0.1 
per  cent  of  nitrogen  (equivalent  to  0.63  per  cent  of  protein),  are 
noted  in  the  subjoined  summary  as  deficient.  If  a  tolerance  of 
1  per  cent  protein  (0.16  per  cent  nitrogen),  is  allowed  the  number  of 
deficient  samples  is  somewhat  reduced  viz.  to  29. 

These  data  appear  in  summary  form  in  Table  IV.

During  the  past  year  the  4-1  per  cent  protein  meal  has  been  the  one 
chiefly  sold  and  nitrogen  has  been  purchased  at  the  best  advantage  in 
this  grade.  Again  it  will  be  noted  that  nitrogen  has  cost  most  in  the 
lowest  grade  product.  The  average  nitrogen  content  of  all  the 
samples  examined  is  close  to  the  guaranty  for  the  medium  grade.

PRECIPITATED   BONE    PHOSPHATE.  33 

LINSEED  MEAL. 

Three  samples,  all  purchased  from  Olds  &  Whipple,  Inc., 
Hartford,    were    submitted    by    Hatheway  &  Steane,  Hartford. 

The  samples  were  20880,  20967  and  20968  and  were  found 
to  contain  5.20,  5.27  and  5.16  per  cent,  of  nitrogen  respectively. 
The  selling  price  was  $54-50  per  ton,  at  which  price  nitrogen  cost 
about  52  cents  per  pound.  This  estimate,  however,  is  based  upon 
very  limited  data;  probably  the  use  of  linseed  meal  in  fertilizers  has 
not  been  extensive. 


II.     RAW    MATERIALS    CHIEFLY    VALUABLE    FOR 
PHOSPHORIC  ACID. 

RAW  ROCK  PHOSPHATE. 

One  sample  was  analyzed  as  follows:

New  Haven.     Stock  of  J.  W.  Alsop,  Avon.

PRECIPITATED  BONE  PHOSPHATE. 

Sixteen  samples  of  precipitated  bone  were  analyzed  and 
analyses  are  given  in  Table  VI. 

So-called  precipitated  bone  phosphate  is  a  by-product  in  the 
manufacture  of  gelatin.  Bones  are  treated  with  acid  to  extract 
mineral  substances  and  when  this  acid  solution  is  treated  with 
milk  of  lime  the  phosphorus  is  precipitated  largely  or  entirely  as 
di-calcium  phosphate,  winch  is  the  precipitated  bone  phosphate 
of  commerce.  Phosphoric  acid  in  tins  material  is  practically  all 
"available." 

The  samples  examined  this  year  have  equaled  or  exceeded  their 
guaranties  in  all  cases  and  the  cost  of  "available"  phosphoric  acid 
at  the  average  of  prices  quoted  ($54-65),  has  been  6.9  cents  per 
pound.

ACID   PHOSPHATE.  35 

DISSOLVED  ROCK  PHOSPHATE  OR  ACID  PHOSPHATE. 

Twenty-one  samples  were  examined  and  analyses  are  given  in 
Table  VII. 

This  material  is  made  by  treating  rock  phosphate  with  sulphuric 
acid  which  results  in  a  conversion  of  the  phosphorus  largely  into 
"available"  form.  In  acid  phosphates  most  of  the  available 
phosphoric  acid  is  soluble  in  water. 

This  commercial  product  is  generally  guaranteed  to  contain 
16  per  cent,  of  phosphoric  acid  in  "available"  forms,  i.  e.,  soluble 
in  water  and  soluble  in  ammonium  citrate  solution.  All  of  the 
samples  examined  during  the  past  season  substantially  met  or 
exceeded  their  guaranties  except  21287  which  was  deficient  by 
0.48  per  cent.  No.  21257  contained  the  guaranteed  amount  of 
available  phosphoric  acid  (10  per  cent.),  but  a  considerable  pro- 
portion of  the  total  was  in  insoluble  form. 

The  prices  quoted  for  "acid  phosphate"  ranged  from  $16.00  to 
$80.00,  the  average  being  $28.45.  At  these  prices  the  cost  per  pound 
of  "available"  phosphoric  acid  has  been  from  4-9  to  9.5  cents,  the 
average  being  7.2  cents.

38  CONNECTICUT   EXPERIMENT   STATION   BULLETIN   250. 

III.     RAW   MATERIALS    CONTAINING   POTASH   AS 
THE  CHIEF  ACTIVE  INGREDIENT. 

Analyses  of  these  materials  are  given  in  Tables  VIII  and  IX. 

CARBONATE  OF  POTASH. 

Four  samples,  all  drawn  by  the  purchasers,  were  examined. 

This  material  is  generally  from  88  to  95  per  cent  pure  and 
contains  from  60  to  65  per  cent  of  actual  potash  (K20).  Of  the 
samples  examined  this  year  two  were  somewhat  below  average 
quality.    No  prices  were  quoted  to  us  for  this  source  of  potash. 

MURIATE  OF  POTASH. 

Eight  samples  were  analyzed  all  but  one  of  which  were  drawn 
by  the  Station  agent. 

This  is  the  potash  salt  which  is  chiefly  imported  for  agricultural 
purposes  and  is  about  80  per  cent  pure,  equivalent  to  50.5  per 
cent  of  actual  potash  (K20).  Because  it  readily  absorbs  moisture 
it  is  frequently  guaranteed  48  per  cent  potash. 

All  the  samples  examined  exceeded  their  guaranties  except  21301 
which  was  somewhat  deficient.  So  far  as  prices  are  known  the 
cost  per  pound  of  actual  potash  ranged  from  4  to  6.2  cents,  the  average 
being  5.0  cents. 

HIGH  GRADE  SULPHATE  OF  POTASH. 

Thirteen  samples  were  examined:  one,  however,  20751,  was 
merely  tested  qualitatively  to  determine  whether  or  not  it  was  a 
sulphate. 

The  commonest  grade  of  this  potash  salt  is  the  one  containing 
about  48  per  cent  of  actual  potash  or  about  90  per  cent  sulphate 
of  potash.  Nos.  21722  and  21009  were  the  only  samples  which 
failed  to  satisfy  their  guaranties. 

No.  21253  contained  less  than  48  per  cent  but  no  statement  of 
guaranty  was  given.  This  sample  contained  a  little  ammonia, 
probably  in  the  form  of  ammonium  sulphate.  At  the  price  given 
us,  potash  in  this  lot  cost  7.9  cents  per  pound,  which  is  the  extreme 
figure  found  this  year.  Excluding  this  sample,  the  cost  per  pound 
of  potash  from  this  source  has  ranged  from  8.9  to  6.1  cents  and 
averaged  5.3  cents. 

KAINIT. 

Only  one  sample  was  analyzed.  It  fully  met  its  guaranty  and  at 
the  price  quoted  ($20.00),  potash  cost  the  purchaser  8  cents  per  pound. 

The  potash  in  kainit  is  combined  largely  or  entirely  with  chlorine 
and  a  considerable  amount  of  common  salt  (sodium  chloride)  is 
also  present.  For  this  reason  the  use  of  kainit  is  avoided  in  mixed 
fertilizers  intended  for  tobacco  in  this  State  where  wrapper  leaf 
is  largely  grown.

DOUBLE  SULPHATE  OF  POTASH  AND  MAGNESIA  OR  "DOUBLE 
MANURE  SALTS." 

Eleven  samples  were  analyzed.  Three  were  sampled  by  the 
Station  agent  and  eight  were  submitted  by  the  purchasers. 

This  salt  was  a  familiar  source  of  potash  before  the  war.  A  few 
samples  were  found  among  our  dealers  in  1922  and  a  larger  number 
were  collected  this  year.  Potash  from  this  source  is  favored  by 
tobacco  growers  not  only  because  it  is  relatively  free  from  chlorine 
but  because  it  also  carries  a  considerable  amount  of  magnesium. 

Last  year  a  product  called  "Manure  Salts"  appeared  on  the 
market  which  was  mistaken  by  some  purchasers  for  the  "Double 
Sulphate"  or  "Double  Manure  Salts."  It  was  found  that  the 
"Manure  Salts"  was  quite  a  different  article;  it  contained  much 
chlorine  and  little  magnesia.  No  samples  of  the  product  were 
found  during  the  past  season. 

Potash  in  the  double  sulphate  is  generally  guaranteed  at  26 
per  cent  and  the  samples  examined  have  exceeded  that  figure 
except  in  two  cases  viz.,  20851  and  21061,  where  deficiencies  of 
1.76  and  0.29  per  cent  respectively  were  found.  Samples  20852, 
20879,  20978  and  probably  also  20868  contained  high  percentages 
of  potash  due  to  accidental  mixture  with  high  grade  sulphate. 

Prices  are  not  available  in  all  cases  but,  excluding  20868  for  the 
reason  just  given,  the  range  has  been  from  5.8  to  8.0  cents  per  pound 
for  actual  potash.  The  average,  excluding  the  four  abnormally  high 
samples,  based  upon  the  average  of  three  prices  is  7  cents  per  pound. 

IV.    RAW  MATERIALS  CONTAINING  NITROGEN  AND 

POTASH. 

Two  samples  of  "Nitrapo",  Nos.  20648  and  21401,  both  pur- 
chased from  the  Nitrates  Agencies  Co.,  New  York,  by  E.  N. 
Austin,  Suffield,  were  analyzed.  One  of  the  samples  was  drawn 
by  the  Station  agent  and  the  other  was  submitted  by  the  pur- 
chaser. 

Two  samples  called  Nitrate  of  Potash  were  examined  but  they 
were  not  pure  nitrate  of  potash,  but  "Nitrapo"  or  material  of  the 
same  type.  One  of  these,  20954,  was  sampled  by  the  Station  agent 
from  the  stock  of  Apothecaries  Hall  Co.,  Waterbury.  The  other, 
20610,  was  submitted  by  H.  M.  Rogers,  Southington. 
Analyses  are  as  follows:

DRY   GROUND   FISH.  43 


V.    RAW   MATERIALS   CONTAINING   NITROGEN   AND 
PHOSPHORIC  ACID. 

DRY  GROUND  FISH. 

Forty-nine  samples  of  dry  ground  fish  have  been  analyzed 
during  the  year.  Of  these  seventeen  were  sampled  by  the  Station 
agent  and  thirty-two  were  submitted  by  purchasers.  Analyses 
are  given  in  Table  XI. 

This  material  is  generally  guaranteed  to  contain  8.23  per  cent  of 
nitrogen  and  5  to  6  per  cent  of  phosphoric  acid.  In  a  number  of 
cases  guaranties  were  not  furnished,  but  in  none  of  these  were  the 
nitrogen  and  phosphoric  acid  found  less  than  the  amounts  usually 
guaranteed.  Of  those  samples  with  guaranties,  eight  were  defi- 
cient in  nitrogen  by  amounts  exceeding  0.1  per  cent.  The  diffident 
samples  were  as  follows : 

Station  Deficiency  in 

No.  ■  Nitrogen 

21266  0.21% 

21219  0.17 

20436 0.84 

20437 0.17 

20439  0.26 

20564  0.22 

20565  0.12 

20791 0.14 

None  of  the  samples  were  deficient  in  phosphoric  acid. 

The  price  has  varied  between  the  rather  wide  limits  of  $58.00 
and  $80.00  only  one  quotation  of  the  high  figure  being  recorded. 
The  average  of  prices  quoted  confidentially  or  otherwise,  is  $64.90. 

The  averages  for  nitrogen  and  phosphoric  acid  are  8.64  and  7.86 
per  cent  respectively  which  makes  the  cost  per  pound  of  nitrogen  31.5 
cents,  allowing  6  cents  per  pound  for  total  phosphoric  acid. 

Chlorine  Content  of  Dry  Ground  Fish. 

Chlorine  was  determined  in  forty-eight  of  the  samples  examined 
this  year.  Two  samples,  20704  and  21402  were  found  to  contain 
3.25  per  cent  and  2.63  per  cent  chlorine  respectively.  Excluding 
these  two,  the  remaining  samples  may  be  summarized  as  follows : 

Maximum 0. 74% 

Minimum 0. 14 

Average. 0. 25 

The  salt  content  of  this  product  does  not  appear  to  be  a  matter 
of  serious  consideration,  at  least  so  far  as  the  domestic  product  is 
concerned.  We  understand  that  fish  manures  from  foreign  sources 
may  run  higher  in  this  particular,  but  we  have  no  information  as 
to  whether  or  not  the  two  samples  already  mentioned  which  con- 
tained excessive  amounts  of  salt  were  imported  products.

GROUND    BONE.  49 


TANKAGE. 

Ten  samples,  all  drawn  by  the  Station  agent  have  been  examined 
and  results  are  given  in  Table  XII. 

Only  one  of  these  samples  was  sold  as  "bone  and  meat"  tankage 
but  most  of  the  others,  by  their  phosphoric  acid  content,  show  the 
presence  of  a  considerable  proportion  of  bone.  Tankage  with  high 
phosphoric  acid  is  relatively  low  in  nitrogen. 

The  utility  of  the  plant  food  in  this  material  depends  to  an  im- 
portant degree  upon  its  mechanical  condition.  In  five  of  the 
samples  examined  more  than  one-half  of  the  material  was  finer  than 
one-fiftieth  of  an  inch.  The  fertilizer  ingredients  in  these  will  be 
more  readily  utilized  than  in  the  case  of  coarser  products. 

There  is  no  consistent  comparison  in  the  cost  of  plant  food  in  the 
several  grades  of  this  product.  Taking  the  four  cases  in  which 
prices  are  given,  three  of  them  representing  goods  of  about  the 
same  degree  of  fineness,  and  assuming  a  uniform  value  of  6  cents 
per  pound  for  total  phosphoric  acid,  the  cost  per  pound  of  nitrogen 
in  20910  which  contains  the  least  bone,  is  31  cents.  In  the  other 
three,  which  contain  relatively  large  amounts  of  bone,  nitrogen  has 
cost  from  17.3  to  24.5  cents  per  pound. 


GROUND  BONE. 

Twenty-eight  samples  of  ground  bone  were  examined,  thirteen 
of  which  were  drawn  by  the  Station  agent  and  fifteen  were  sub- 
mitted by  purchasers.     The  results  appear  in  Table  XIII. 

Ground  bone  is  a  very  desirable  form  of  plant  food  where  imme- 
diate availability  is  not  essential.  It  is  used  to  advantage  for 
seeding  down  and  for  certain  crops  which  require  a  long  season  in 
which  to  mature.  Like  tankage  the  mechanical  condition  of  the 
bone  meal  is  important.  Of  the  twenty-eight  samples  analyzed 
this  year,  in  twenty-one  50  per  cent  or  more  of  the  material  was 
finer  than  l/50th  of  an  inch;  in  ten,  70  per  cent  or  more  was  of 
that  degree  of  fineness.  Three  samples  were  very  coarse,  30  per 
cent  or  less  passing  l/50th  mesh. 

Two  samples,  21181  and  21251  were  deficient  in  nitrogen  by  0.16 
per  cent  in  each  case.  Samples  20915  and  21054  failed  to  meet  their 
guaranties  for  phosphoric  acid  by  1.30  and  3.68  percent  respectively. 

The  average  nitrogen  content  of  all  samples  is  3.91  per  cent  and 
the  average  amount  of  phosphorc  acid  found  is  24.67  per  cent.  At 
the  average  of  prices  quoted  ($4-8.  j.1),  allowing  22  cents  per  pound  for 
nitrogen,  phosphoric  acid  from  this  source  has  cost  6.3  cents  per  pound.

MIXED    FERTILIZERS    CONTAINING    NITROGEN    AND 
PHOSPHORIC  ACID. 

Only  seven  of  the  nitrogenous  superphosphates  examined  this 
year  were  without  potash.  The  analyses  of  these  are  given  in 
Table  XIV. 

It  has  become  widely  established  in  trade  practice  to  designate 
the  grade  or  quality  of  mixed  fertilizers  by  stating  as  a  part  of 
the  brand  name,  or  instead  of  it,  the  guaranteed  amounts  of 
plant  food  contained  in  the  mixture.  Thus,  Berkshire  Tobacco 
Starter,  6-4-0  means  that  the  mixture  carries  6  per  cent  of  ammonia 
(NH3),  4  per  cent  of  available  phosphoric  acid  (P2O5),  and  no 
potash  (K20).  In  order  to  enable  the  purchaser  to  more  readily 
compare  the  results  of  our  analyses  with  the  claims  of  the  manu- 
facturer our  tables  of  analyses  of  mixed  fertilizers  have  been 
somewhat  revised.  The  figures  in  the  column  headed  "Grade" 
represent  the  manufacturer's  claim  or  guaranty  as  to  ammonia, 
available  phosphoric  acid  and  potash  in  the  order  named  and 
the  corresponding  ingredients  found  by  our  analysis  appear  in 
the  tables  in  bold  face  type.  To  apply  the  interpretation  in  the 
instance  just  cited,  Table  XIV,  No.  21335,  Berkshire  Tobacco 
Starter  .claimes  to  contain  6  per  cent  of  ammonia,  4  per  cent  of 
available  phosphoric  acid  and  no  potash;  and  it  appears  from  the 
analysis  that  6.4  per  cent  of  ammonia  and  4.53  per  cent  of  available 
phosphoric  acid  were  found.  No  tests  were  made  for  potash  as 
none  was  declared. 

Two  samples  were  found  deficient  in  ammonia;  they  were: 

21498.  Blish  Hardware  Co.  Top  Dressing  for  Grass  7-4-0, 
ammonia  deficiency  0.3  per  cent. 

21133.  Shoemaker  Swift-Sure  Superphosphate  Tobacco  Starter 
4-10-0,  ammonia  deficiency  0.3  per  cent. 

A  second  sample,  21318,  of  the  last  named  brand  was  found  to 
fully  meet  its  guaranty. 

MIXED    FERTILIZERS   CONTAINING   NITROGEN,    PHOSPHORIC 
ACID  AND  POTASH. 

Analyses  of  two  hundred  and  seventy  samples  of  fertilizers  of 
this  class  are  given  in  Table  XVI.  Nine  of  these  were  sampled 
by  purchasers  and  the  remainder  were  official  samples  drawn  by 
the  Station  agent. 

To  facilitate  the  comparison  between  composition  guaranteed 
and  that  found  the  same  change  in  the  arrangement  of  analyses 
has  been  made  as  has  already  been  described  under  the  preceding 
heading,  Mixed  Fertilizers  Containing  Nitrogen  and  Phosphoric 
Acid. 

Samples  Failing  to  Meet  Guaranties. 

A  large  proportion  of  the  fertilizers  in  this  group  have  failed  to 
meet  their  guaranties  in  all  respects.     Of  the  two  hundred  and 


MIXED   FERTILIZERS.  55 

sixty-one  officially  drawn  samples,  one  hundred  and  eighteen,  or 
about  45  per  cent,  were  deficient  with  respect  to  one  or  more  of 
the  guaranteed  ingredients,  deficiencies  of  0.12  per  cent  or  less  in 
ammonia,  0.20  per  cent  or  less  in  available  phosphoric  acid  and 
0.15  per  cent  or  less  in  potash  being  disregarded  in  arriving  at 
these  figures.  The  number  of  ammonia  deficiencies  was  greater 
than  the  numbers  of  phosphoric  acid  and  potash  deficiencies 
combined.  Ninety-four  samples,  or  36  per  cent  were  deficient 
in  one  ingredient;  twenty-four,  or  9.2  per  cent  were  deficient  in 
two  ingredients;  but  none  were  found  lacking  in  all  of  the  in- 
gredients guaranteed. 

While  it  is  true  that  many  of  these  deficiencies  are  not  large, 
perhaps  even  within  the  range  of  analytical  differences  which  occur 
between  experienced  analysts,  nevertheless  it  seems  clear  that 
manufacturers  too  often  fix  guaranties  with  an  insufficient  margin 
of  safety. 

From  the  purchaser's  standpoint,  however,  there  may  be  a 
compensating  consideration  because,  in  many  cases,  a  shortage 
in  one  item  of  plant  food  is  accompanied  by  an  over-run  in  one 
or  both  of  the  other  items  and  a  loss  in  money  value  does  not 
necessarily  occur.  If  ammonia,  available  phosphoric  acid  and 
potash  are  valued  at  about  the  average  of  what  they  have  cost 
in  the  various  raw  materials  which  we  have  examined,  viz;  30,  7 
and  5.5  cents  per  pound  respectively,  the  number  of  brands  thus 
shown  to  be  deficient  in  money  value  is  reduced  to  seventy-seven. 
Of  these  seventy-seven  the  shortage  in  money  value  in  thirty-one 
brands  is  less  than  one  dollar  per  ton;  but  in  forty-five  brands, 
or  about  17.0  per  cent  of  the  official  samples  in  this  group,  the 
shortage  is  one  dollar  or  more  per  ton.  This  proportion  is  much 
greater  than  usual.    The  deficient  brands  are  listed  in  Table  XV.

Analyses  Requiring  Special  Notice. 

Manufacturers  or  jobbers  occasionally  request  that  a  second 
sample  be  secured  and  analyzed  in  case  our  first  analysis  has 
shown  a  deficiency  and,  so  far  as  possible,  we  have  granted  such 
requests. 

21027.  National  Complete  Tobacco,  5-4-5,  was  deficient  in 
ammonia  and  the  second  sample,  21329,  was  likewise  deficient. 

21021.  National  Premier  Truck  Manure,  4-8-7,  was  deficient 
in  potash  and  the  second  sample,  21320,  was  also  deficient  in 
this  respect. 

21012.  Armour's  Big  Crop,  4-6-10,  was  deficient'  in  ammonia 
and  available  phosphoric  acid  on  the  first  analysis.  The  second 
sample,  21433,  was  deficient  in  ammonia  and  potash. 

21045.  Armour's  Big  Crop,  4-8-4,  was  low  in  available  phos- 
phoric and'  the  second  sample,  21322,  was  low  in  potash. 

21047.  Armour's  Big  Crop,  5-8-7,  was  low  in  potash.  A  second 
sample,  21321,  was  found  not  to  conform  at  all  to  a  5-8-7  grade 
and  partial  analysis  of  the  duplicate  left  by  our  agent  with  the 
person  whose  stock  was  sampled  failed  to  show  any  error  in 
sampling.     No  further  samples  of  this  brand  could  be  secured. 


MIXED   FERTILIZERS.  57 

Evidently  another  grade  of  goods  had  been  put  in  bags  marked 
5-8-7  by  mistake. 

21183.  Atlantic,  4-8-6,  was  deficient  in  ammonia  and  potash 
but  the  second  sample,  21552,  was  deficient  in  ammonia  only. 

21293.  Clark's  Special  Tip  Top,  5-8-5,  was  deficient  in  am- 
monia and  the  second  sample,  21436,  was  also  deficient  in  this 
respect. 

21298.  Essex  Market  Garden,  4-8-4,  was  low  in  ammonia 
but  the  second  sample,  21435,  fully  met  the  guaranty  in  all  re  - 
spects. 

21092.  Frisbie's  Market  Garden,  4-8-6,  was  low  in  ammonia 
and  the  second  sample,  21267,  was  likewise  deficient. 

21099.  Frisbie's  Special  Vegetable,  4-8-4,  was  low  in  both 
ammonia  and  potash  but  the  second  sample,  21265,  was  deficient 
in  ammonia  only. 

21352.  Frisbie's  Tobacco  Manure,  5-8-6,  was  low  in  ammonia 
but  the  second  sample,  21574,  met  the  guaranty. 

21380.  Mapes  Tobacco  Ash  Constituents,  1-4-15,  was  deficient 
in  potash;  the  second  sample,  21458,  contained  about  2  per  cent 
more  potash  but  it  was  still  under  guaranty. 

21103.  Mapes  Top  Dresser,  10-4-2,  was  low  in  ammonia;  the 
second  sample,  21153,  was  also  low  in  this  respect. 

20960.  Mapes  Tobacco  Starter,  5-6-1,  was  low  in  ammonia 
but  the  second  sample,  21268,  satisfied  the  guaranty. 

Classification  of  Grades  with  Particular  Reference 
to  Ammonia. 

Attention  has  been  called  in  previous  reports  to  the  relatively 
higher  cost  of  nitrogen  in  low  priced  goods  carrying  low  guaranties 
of  ammonia.  It  was  shown,  for  example1,  that  the  cost  per  pound 
of  nitrogen  in  goods  guaranteed  1  per  cent  ammonia  (0.82  per  cent 
nitrogen),  was  from  two  and  one-half  to  three  times  greater  than 
in  brands  carrying  3  to  5  per  cent  ammonia  (2.47  to  4.11  nitrogen). 
A  gradual  reduction  in  the  proportion  of  low  nitrogen  brands  is 
shown  by  summaries  for  the  last  three  years  as  follows :

58  CONNECTICUT   EXPERIMENT   STATION    BULLETIN   250. 

The  number  of  samples  carrying  guaranties  of  from  4  to  5 
per  cent  ammonia  comprised  over  50  per  cent  of  the  total  number 
this  year. 

The  "New  England  Standard  Nine." 

At  a  meeting  in  Boston  in  the  latter  part  of  December,  1922,  New 
England  agronomists  and  representatives  of  fertilizer  manufac- 
turers discussed  and  finally  adopted  a  list  of  high  analysis  fertilizers 
which,  it  was  felt,  would  adequately  meet  all  the  reasonable  needs 
of  farmers  in  the  New  England  states.  It  has  long  been  recog- 
nized that  the  great  multiplicity  of  brands  now  on  the  market, 
many  of  which  differ  from  one  another  but  very  slightly,  is  an 
economic  disadvantage  in  that  it  adds  to  the  cost  of  manufacture 
and  distribution  of  fertilizers  and  serves  no  real  agricultural  need. 
However,  competition  is  keen  in  the  fertilizer  business  and  many 
brands  have  established  good  will  values  which  their  manufac- 
turers do  not  wish  to  sacrifice.  Manufacturers  will,  therefore, 
continue  to  emphasize  brands  until  purchasers  more  generally 
think  in  terms  of  grades.  It  was  the  sense  of  this  New  England 
conference  that  the  nine  grades  chosen  would  satisfy  present  re- 
quirements and  that  they  should  be  advocated  until  there  is 
evidence  that  revision  of  the  list  should  be  made. 

The  formulas  adopted  and  now  known  as  the  "New  England 
Standard  Nine"  and  the  number  of  mixed  fertilizers  examined 
by  us  this  year  winch  fall  in  these  respective  grades  are  as  follows : 

Standard  Number  of 

Grade  samples.

2-12-4 2 

3-10-4 1 

3-10-6 0

4-8-6 12 

5-4-5 23 

5-8-7 14 

8-6-6 1 

Total 84 


These  figures  show  that  of  two  hundred  and  sixty-one  "com- 
plete" fertilizers  and  two  containing  only  phosphoric  acid  and 
potash,  one  hundred  and  seventy-nine  do  not  fall  in  any  of  the 
nine  grades  here  given  although  many  of  them  approach  these 
grades  more  or  less  closely.  Only  four  of  the  adopted  grades  are 
represented  by  any  considerable  number  of  samples  and  one  grade 
is  not  represented  at  all.  However,  as  the  purpose  of  these  nine 
grades  becomes  better  known  among  manufacturers  and  users  of 
fertilizers  their  representation  will,  no  doubt,  increase.

Availability  of  the  Organic  Nitrogen. 

Only  three  samples  showed  deficiencies  in  the  quality  of  the 
insoluble  organic  nitrogen  by  both  the  alkaline  and  the  neutral 
methods  of  evaluation.  In  these  cases,  however,  the  amounts  of 
insoluble  organic  nitrogen  were  small  (.4  to  .5  per  cent),  and  the 
total  nitrogen  was  in  excess  of  the  guaranty  in  all  cases,  the  ex- 
cesses being  greater  than,  or  practically  equal  to,  the  inactive 
nitrogen  found.

SPECIAL  MIXTURES  AND  HOME  MIXTURES. 

In  Table  XIX  are  given  analyses  of  special  mixtures  prepared 
by  manufacturers  according  to  specifications  furnished  by  the 
purchasers  and  also  of  home  mixtures  prepared  by  individuals  or 
firms  from  raw  materials  purchased  by  them.  Twenty-six  samples 
of  these  types  were  analyzed.  Ten  of  these  were  sampled  by  the 
Station  agent  and  the  remainder  were  submitted  by  the  con- 
sumers. 

In  some  cases  formulas  were  submitted  with  the  samples  and 
they  are  given  in  Table  XVII.

POTASH-MARL. 

21426.  One  sample  of  Potash-Marl  manufactured  by  the 
Potash-Marl,  Inc.,  New  York,  was  taken  by  the  station  agent  from 
the  stock  of  Lightbourn  &  Pond  Co.,  New  Haven. 

This  is  prepared  from  green  sand  marl  and  may  contain  six  per 
cent  or  more  of  potash  not,  however,  in  water-soluble  form.  Only 
phosphoric  acid,  of  which  it  contains  an  inconsiderable  amount,  is

These  materials  particularly  21596  and  21597,  should  be  valu- 
able as  absorbents  and  for  composting  with  manure;  the  economy 
of  their  use  will  depend,  of  course,  upon  the  cost  of  handling. 

We  can  give  no  opinion  on  the  merits  of  20611  from  the  stand- 
point of  radio-activity.

88  CONNECTICUT   EXPEEIMENT   STATION   BULLETIN   250. 

In  general,  the  fertilizer  ingredients,  i.e.,  nitrogen,  phosphoric 
acid  and  potash,  in  this  kind  of  material  are  inconsiderable.  Its 
chief  usefulness  is  when  applied  to  light,  sandy  soils  which  will  be 
benefited  by  the  humus  which  it  contains. 


MISCELLANEOUS  MATERIALS. 

Soils. 

Nineteen  samples  have  been  submitted.  Tests  were  made  for 
acidity  and  lime  requirement  but  no  further  examinations  were  un- 
dertaken. The  diagnosis  of  soil  troubles  is  a  difficult  and  uncertain 
task  not  to  be  solved  by  the  usual  chemical  analysis. 

Check  Cottonseed  Meals. 

Thirty  samples,  chiefly  cottonseed  meals,  were  examined  and 
reported  to  the  American  Oil  Chemists'  Society  in  connection 
with  their  cooperative  program  in  which  this  laboratory  has 
participated.  The  schedule  involves  the  analysis  of  weekly  sam- 
ples sent  out  by  the  Society  to  various  control  and  industrial 
laboratories  for  the  purpose  of  studying  uniformity  of  methods  and 
technique  in  the  analysis  of  this  class  of  products. 

Check  Fertilizers. 

Eleven  samples  of  mixed  fertilizers  have  been  analyzed  and 
reported  to  the  Royster  Guano  Co.  The  plan  and  purpose  of  this 
cooperative  work  is  similar  to  that  already  explained  for  the  Check 
Meal  series. 

Unclassified. 

Seven  samples  of  miscellaneous  materials  have  been  examined 
which  require  no  particular  comment.
